F03 USE IN THE MANUFACTURE OF WELT-SHOES.

. Patented Apr. 24), 1915.

Application filed May 11, 1914. Serial No. 837,675.

To all whom it may concern:

Be it known that I, citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain novel Machine for Use in the Manufacture of Welt-Shoes.

My invention relates to means, by which the defects are obviated which are caused by the bulging out of the inseam around the toe part of a welt shoe.

In order to produce a welt shoe, in which the edge of the outsole around the toe 1S trimmed uniformly to the edge of the last and upper, the line of the inseam must be in conformity with the original line of the shoulder of the insole. If this is accomplished and the outsole is rounded-up to the line of the inseam, a uniform extension of the edge of the outsole over the edge of the last and upper is produced and the outsole can be stitched to the welt without injuring the stitches of the inseam or without bringing the outsole stitches too near to the edge of the outsole and thereby rendering-them liable to be cut in the trimming of the edges. In most cases where a gem or a soft insole is used the line of the inseam around the toe is pushed out of the original line of the shoulder of the insole in the process of its sewing. ()n shoes of whichthe soles are trimmed close, this results in an irregular extension of the edge of the outsole over the edge of the last and upper, or in the cutting of the inseam stitches with the awl or needle in stitching the outsole to the Welt, or in cutting the outsole stitches in trimming the edges of the outsoles.

My invention has for its object the obviation of these defects. I accomplish this end by pushing back the bulged out inseam and thereby practically bring the line of the inseam in conformity with the original line of the shoulder of the insole. In order to carry out this purpose, I have constructed the hereinafter described machine, whereby the inseamed shoe, with the last in, is readily and easily held in the desired position while the sliding jaws are applied in pushing back the inseam as'above set forth.

I hereby declare that the following is a full, clear and exact description of the machine and its operation, reference being had WILLIAM FOWLER, a

to the accompanying drawings forming part of this description.

Figure 1 is a top plan view of my machine.- Fig. 2 is a side elevation, with a portion of the side standard broken away and the shoe in position. Fig. 3 is a transverse section on the line 3, 3, of Fig. 2, with the shoe removed. Fig. 4 is an enlarged detail of the toe portion of the shoe and the sliding jaws. Fig. 5 is a transverse section of the same. Fig. 6 is a detail, partly in section, showing the holder for the heelof the last. Fig. 7 is a perspective view of the sliding jaws. Fig. 8 is a side elevation of the toe of the shoe, after the operation.

1, 1, are the side standards, suitably braced together'with cross braces to form a substantial framework for the operating mechanism.

The supporting blocks 2, 2, are secured to the side standards. Sufficient space is left between them for the entrance of the shoe. These blocks form a table and a support for the sliding jaws 4, 4. These paws are 'attached by screws 41 to the T-shaped tcnons 5, 5, which are arranged to engage and slide in a correspondingly shaped mortise in the table. The inner edges 7, 7, of these sliding jaws are shaped'to conform, when brought toward the inseam, to'the original line of the shoulder on the toe portion of the insole. For shifting these jaws toward and away from each other across the framework, I provide a toggle lever construction com prising the levers 8, 8, pivoted one to each plate 4, at 9, 9, and also pivotally mounted at 10, 10, on the cross bar 11 of the frame. These two levers are connected together by the toggle levers 12, 12, pivoted together at 13 and at .14, 1-1, one to each lever 8. The knuckle of the toggle levers is connected by a link 15 to the hand is pivoted at 17 on top of one of the side standards. It will be evident that if this hand lever 16 is shifted inwardly, that the toggle levers will be spread outwardly, causing the inner ends of the levers 8, 8, to bring the jaws 4. 4, toward each other, while a movement in the opposite direction will spread the jaws. In order that they may not be spread too far apart, extensions 18,18, are provided for the 1evers8, 8, which contact with stops 19, 19., on the table.

lever 16, which lever J Extending across between the side standards and curved downwardly to give ample clearance for, the inseamed shoe, is a connecting bar 20, in the middle portion of which is mounted an adjustable screw 21, carrying a head or knob 22, which can be raised or lowered by turning the screw 21 in the supporting bar 20.

In the front portion of the framework 1s mounted the heel holder 23, the side walls 24, 24, of which are flared outwardly to receive the heel portion of the shoe, while the.

flange 25 at the bottom supports the shoe.

This heel support is swiveled on a horizontal pin 26 (Fig. 6) pivoted in the block 27, which is in turn swiveled by the vertical pin 28 on a lever 29. This lever 29 is pivoted at 30 on top .of one of the side standards, and a series of holes 31 are provided a short distance apart so that by meansof a removable pin the lever 29 can be pivoted in any one of theseries of holes.' On the opposite side standard,-I have provided a rigidbar 32 engaged by the inner end of a pinch lever 33 pivoted on the lever 29, the purpose of which is to provide for locking the lever 29in any position to which it may be pushed. A stop 34 is also provided to limit the inner movement of the lever The heel holder is located on a lower plane than the toe position, so that when the last is secured I in position, thetoe portion will lie in a horizontal plane.

The tenons 5 of the plates 4 are cut away at 40 so'as not to come in contact with the shoe.

The pivot pins 9, 9, for the sliding jaws are removable, so that otherplates can be readily substituted for various shapes of insole, and 'as many patterns will be provided as there are kinds of shoes to be operated upon. v

The shoes-on which my machine is used are prepared as usual. The insole 35 is" tacked to the last 38. The upper 36 is lasted and the welt 37 is sewed to the upper and insole in the usual way, but in sewing around the toe it frequently happens that the inseam bulges out and, if left in this condition, causes the defects above described. My machine is then brought into operation. The inseamed shoe is placed in the machine as .shown in Fig. 2. The heel portion is located in the holder and supported by the flange The toe portion is inserted underneath the plates 4, 4, which are in the initial position spread apart by maniuplation of hand lever 16. The screw 21 is adjusted so that the knob 22 supports the toe part of the shoe. By releasing the pinch lever 33 and adjusting the lever 29, the shoe is firmly held by the heel holder and the toe plates with the edges 7, 7 of the sliding jaws 4, 4, bearing just outside the inseam 39. The shoe is firmly held in this position by the heel holder and. the toe support. The hand lever 16 is then actuated to set the sliding jaws into operation and push the inseam toward the original line of the shoulder of the insole and therewith practically bring the line of the inseam in conformity with the original line of the shoulder of the insole.

While I have shown only one construction of mechanism to accomplish the desired result, which is the obviation of the said defects, it will be evidentthat many modifications of the general structure will readily suggest themselves, but inasmuch as the fundamental and the most important part of my invention consists in the discovery of the fact-that the defects above set forth can be obviated by pushing back the bulged out inseam to the original line of the shoulder of the insole, I do not desire to be limited to the particular construction shown.
